To all whom may concern! Be it known .that. 1, JAN STEYNIS, a subject of the Queen of the Nether1ands,,residing at Bay Shore, county of Suiiolk, State 5 of New York, have invented certain new port, of any suitable character, in whichare positioned a number of ozone generating. tubescontainmg inner and outer electrodes, The outer electrodes may be connected to one terminal a separated by dielectric tubes.

of a suitable source of current-in any desired manner, as by being grounded through the supporting casing. The inner electrodes r of the current source. 7

plied to the electrodes, streaming electrical discharges take. place and the air which is passed through the tubes,- is thereby ozonizedQ Suitable means may also be provided for cooling the J generating tubes.

With such an apparatus as I have described above, it sometimes happensthatthe dielectric between the inner and outer electrodes breaks down or a short circuitoccurs through the'presence of moisture, or for some other reason it becomes necessary to withdraw theelectrodes from the supporting tubes for cleaning or repairing purposes. My invention is especially-concerned with providing an arrangement whereby this removal of the electrodes may be easlly accomplished when desired. The particular means whereby this is effected will be fully described'herein, but in general it may be said'that theelectrodes and dielectrics 'in each tube are parted at the middle, so that one set may be withdrawn from either end.

In'the' drawings, Figure 1 is a longitudinal sectional-view of. my improved appahereinafter' appear, in View, I have provided an apparatus consisting of acaslngorsupi are connected in series to the other terminal,

As current is ap-.

ratus. Fig. 2 is an end elevation partlyin sectlon, showing the apparatus with one of the air chambers or casings removed. Fig. 3 is a longitudinal sectional view of a single tube and its contents on an enlarged scale; Fig. at is a section taken on the line 4.l of Fig. 3; and Fig 5 isga fragmentary sectionalview of the device shown in Fig. .3 and is intended to show the details-of connectlon between the inner ends of the two 5 inner electrodes. i

Referring to Fig. 1, 10 indicates the support or casing for the generating tubes. This casing is provided at either end with means for supportingplatesofglass 11, 12, so that the ozone generating apparatus may be entirely inclosed, but may still be open to view from without. Near the ends of the casing 10 arethe'plates 13, 14 in which the V, generating tubes 15 are supported. members- 16, 17 positioned between the plates 13,14 also assist in the. support of these tubes V Referringnowparticularly'to F ig. 3, it is seen that each of the tubes 15 is 'su'rround- 3e ed by a jacket refer some suitable cooling if medium, such as; ammonia gas. If desired, these jackets may be packed in some su material as powdered cork. The outer-"tu bular electrodes-19 may be inserted intoa-f tube 15 from either end. Each electrodelSIf is'provided at one end with a flange or collar 1'9" for limitingits movement into the.

tube, and if desired, some suitable means maybe applied to these collars, for retaining the electrodes within the tubes 15. Fitting into the outer electrode-i 19 are the dielectric tubes 20 which are also insertible from either end of any generating. tube. These dielectric tubes may be made of any suitable insulating material. The innerelectrodes-.21 are located within the dielectric tubes20 and are provided with suitable'enlargements or flanges 22 along their length, V as is customary. a f

Some suitable means is provided for cen tering and retaining the inner electrodes within their; respective dielectric tubes. As shown herein these means comprise a plu-f rality' of radially movable rods of porcelain or other insulating material, {which are" surface of the dielectric 'tubesl- I havepro tubes.

vided means for moving these rods radially outward, which means comprises a coneshaped member 24 which is screw threaded at 25 in the end of the inner electrode. It is obvious that by screwing the cone-shaped member 24 toward the center of the inner electrode, the rods 23 which contact with the cone-shaped member will all be forced an equal distance radially outwarduntil they contact with the dielectric tube, thus centering and retaining the electrode therein.

The cone-shapedexpanding members are also utilized as means for supporting the rods 26 to which theelectrical conductors 26 are connectedto connect in series the inner electrodes in the different generating One of the cone-shaped members used upon an inner end 'of one of the electrodes within each tubeis formed somewhat difl'erently from the remalmngconeshaped members, as fshownfin Fig. 5. Here the cone-shaped member 27 is seento be provided with an internal cone-shaped recess 28, in which the cone-shaped end 29- of the rod is adapted to fit. This rod 30 may be connected tothe cone-shaped member. 24 111 any suitable way, as by being screw threaded lthereinand serves when the parts are in position to electrically connect the two inner electrodes within the same tube. The purpose of providing the corresponding coneshaped surfaces 28 and 29 is in order that when the two inner electrodes are inserted within the tube from opposite ends the end 29 of the rod 30 will automatlcally pos1t1on itself within therecess in the member 27 to viously' pointed out, they will be automatically electrically connected by the rod 30.

Bolted or otherwise secured to the'plates 13, 14 at the ends of the generating tubes, are the casings 31, 32, the former being two in number and located at the'point of en-, trance and'the point of exit of the air to be ozonized and the latter being herein shown as four in number and each serving to form a passage for air from one tube to an 'ad-' jacent tube. The particular arrangement of these casings or chambersis not important. These chambers are provided with openings opposite the ends of the various tubes and with glass plates '33 removably covering these openings. If it is desired to remove 5 the members from within one ofthe gen- .tive whereit is most needed.

crating tubes, it may be easily done, by removing the proper glass plates 11, 12 and 33, and disconnecting theproper conductor 26.

In Fig. 1, 34 represents a conductor leading from one terminal of any suitable source of current. This conductor as shown is connected at 35 with one end of one of. the

with by means of the rods 30 and conductors 26 as above indicated. The outer electrodes are connected to the other terminal of the source of current in any suitable manner, but it has been found simple and advantageous to ground the-other terminal of the source of current and to connect the 'outer electrodes thereto by grounding through the supporting frame or casing 10.

The operation of my improved device is as follows: Current having been applied to the electrodes from its source, the air to be ozonized is introduced into the apparatus through the pipe or conduit 36. This air passes through the various generating tubes successively and is emitted from the conduit 37 in the form of ozone or ozonized air. In

order to keep the temperature of the electrodes as low as possible, in spite of the streaming discharges which occur between them, ammonia gas or another suitable cooling medium is applied through the pipe or conduit 38 to the jackets 18, which are connected in series andafter passing through these jackets flows off through the pipe 39. It is to be noted that it is preferable that the cooling medium be introduced near that the cooling medium may be most effec- The various advantages of my improved construction will be obvious to one skilled in the art from the above description. Attention is directed particularly, however, to the fact that the various members of the ozonizing devices may be removed in sets from either end of the generating tubes, without the slightest difficulty whenever it ing or repairing.
